This invention relates'tofirearins of the shotguntype, and certainfeatures of the 1nvention find peculiar adaptation in firearms of theover and under type,"such as disclosed in the John M. Browning PatentsNos 1,- 578,638-9. 1 y l The aim` of the invention is to provide afirearm ofthe character described with various features! of novelty andadvantage, thereby providing a betterfirearm and reducing its cost ofmanufacture.

An important object of the invention is to provide, in a gun of the overand under type, an'improved, simplified and effective arrangement bymeans ofV which the extraction of a discharged shell from the barrel inwhich it has been fired, and the retraction but not the ejection) of anunred shell are effected when the gun is broken.

Other objects will be in part obvious and in part pointed out more indetailher'einafter.

The invention accordingly consists in the features of construction,combination of elements and arrangementof parts which-will beexemplified in the construction hereinafter set forth, and the scope ofthe application of which will be indicated in the appended claims. y n

In the accompanying drawings, wherein is shown, for` illustrativepurposes, one ofthe many embodiments which'the present inven- 'tion maytake Figure l is a view looking at the left hand side of the firearm,the stock being broken away to show theV firing mechanism within thereceiver, the left 4hand side wall of the receiver being taken Vinylongitudinal vertical section substantially on line 1-1 of Fig. 3, partsof' the take-down bracket being broken away; y

Referring to the drawings in detail, the barrel sec-tion and thereceiver are generally similar in construction to the correspondingparts illustrated in the said Browning patents. The barrel' section (sotermed for convenience) has a breech piece 25, an over bar- .rel 26,yand an under barrel 27. The receiver has a pair of forwardly extendingparallel sidewalls 28 at the forward lower cornersof Abearing surface24. The bearing element is adapted to be received by a two-partbearingVon the barrel section. One vof these parts is provided by the forwardlyfacing recess or groove 30 at the forward lower corner of the breechpiece and adapted to receive the pin 29. The other part of the bearingispro'- vided by a semi-circular recess 3l on the rear end of thetake-down bracket 32 and adapted to receive the correspondingly curvedsurface 24 of the receiver. This takelown-bracket is generally similarin construction,arrangement and operation to that disclosed in the saidBrowning patents. It comprises 'a relatively narrow rectangular piece orblock slidably mounted on the barrel sectionwso as -to permit ofseparation of the bearing yparts for the hinge element. To thisend,there is pro vided onV the under barrel, just forwardly of the breechpiece, a depending lug 33 having avlongitudinal groove 34 at each side.Slidably engaging in these grooves are ribs V35 on the bracket. Pivotedto the bracket is a take-down lever 36, the forward end of which has asliding catch 37 provided with a hook 38 adapted to cooperate with aledge 39 on the bracket. The lever has a locking lug 40 which is adaptedto take in behind the lug 33 when the lever is in the locking positionshown in Fig. 1. Pivoted to the rear end of, and extending rearwardlyfrom the bracket, is a cocking lever link 41 which is gener lly similarin construction and' function to the corresponding link, designated vbythe numeral 8, in the Browning Patent No. 1,578,638. rlhe numeral 45designatesthe forearm which is connected to, so as to slide' with, thetake-down bracket by a screw or bolt 46. i

The gun is locked in its closed position by `a locking bolt mounted forsliding movement in the receiver beneath the portion 51 which forms avertical bearing in which the stem or post 52 of the top lever 53 isjournalled. The locking bolt is provided with a transverse notch 54:which receives an eccentrically positioned pin 55 depending from thelowei` end of the top lever post 52. This arrangement is generallysimilar to that shown in the said Browning Patent No. 1,578,638.

The locking bolt further has a longitudinally extending and centrallypositioned slot 56 m through which extends the rear endV or arm 60 of acocking lever 61. This cooking lever is pivoted on a pin 62 beneath theltop `lever post and `has a forwardly extending arm 63 which is adaptedto cooperate with the heretofore described link 41 in a manner similarto that disclosed in the said Browning patents.

mechanism which is located in an opening of the frame-like portion ofthe receiver. In the present instance, this firing mechanism is shown ashaving a left hand `hammer 71 yand a right hand hammer 72 which arerespectively control-led by separate triggers 73 and '74%. It is to'beunderstood, however, that this disclosure is by way of illustra-tiononly and, if desired, a single trigger, such asshown in the saidBrowning` patents, may be employed for controlling both' of the hammers.The hammers are pivotally mounted between a pair of ears 75 on a pintle76.

The opposed faces of the hammers are recessed so as to accommodate therear Vupwardly extending end of the coclring lever which is rearwardlyof the pintle 76, clearly shown in Figs. 1 and 2. The rear-end of thecocking lever has a toe 79 which isfadapted to engage shoulders '80 onthe hammers so that, when the gun is broken, each hammer, in the eventthat it has been tired, will be moved to cocked position, shown in Fig.The rear end of the cocking lever, Vwhen the gun is broken, engagesinthe slot 56 in the locking bolt so as to hold the locking bolt inretracted position (see Fig. 2).

Reference will now behad to the ring Associated with each hammer is asear 81 respectively controlled by means of the triggers throughconnectors 82. It will be noted that each trigger has a lug 83 which isbeneath the rear end of the locking boltl when the latter is retractedso that the triggers cannot be pulled when the gun is broken. The searsare urged into operative position by springs 85, and the Vh ammersare'actioned, `when released, by springs 86 about the VSlidably mountedon the frame rearwardly ofthe top lever 53 is a safety device which hasa. particularly simple and effective arrangement. It has a thumb-piece90 with -a pin 91 extending through a slot 92 in .the top portion of theframe. On the under side of this top portion is a groove '93 in which isslidably mounted a latch block 94 which is resiliently held in .place bya vspring 95 about the pin 91. The block has, at its forward end, adepending lug `96 which, when the safety device is in safe or onposition (as shown in Fig.2) lies above .the upper ends of theconnectors so that the triggers can-not be pulled. `When thesafety-device is moved forwardly to the "otlwposition shown in Fig.

1, this lugfis'forwardly of the connectors so that the triggers may bevpulled to lire the gun. The rear end .of thevblock has 4alignedprojections 97 (see Fig. 10) which are adapted to engage in a notch 98when the safety is in on position and to engage in a forward notch 99when the safety is in off position.

-Reference will now be lhad-to the mechanisms forejecti-ng fired shellsand retracting, without ejecting, unfired 4shells from the bores of thebreech piece when the gun is broken. Separate ejecting mechanism isprovided for each barrel, but as these mechanismsare similar inconstruction and operation, a description of one will apply to theother. For convenience, the ejecting mechanism, associated with the overbarrel, will here be described, .and the corresponding parts of theejecting mechanism for the under barre-l willV be Vdesignated by similarreference numerals primed. lThe extractor proper for the over barrel hasa plate of the usual form with a flat stem 106 which fits Y in alongitudinally extending dovetail groove 107 in the vbreech piece. Boththe groove 107 and the stem or shank 106 are dovetailed or undercut soas to hold the extractor inposition for sliding movement. The forwardend of the stem 106 has an enlarged portion 108 which overlies andengages the side o-f the breech piece so as to prevent excessivewobbling or canting movement of the extract-or, it being necy essary tohave sufcient play between the stein lli) from the groove, the bottom ofthe groove has an elongated recess 109 and extending through theenlarged port-ion 108 of the stem is a screw 110, the inner end of whichengages in this recess. Immediately in front of the extractor andmounted for'sliding movement in the same groove 107 is an auxiliarypiece 111 through which the extractor is operated. In the presentillustrative disclosure, this auxiliary piece has an undercut rib 112slidably engaging in the groove y107 and the extent of movement of thispiece is limited'by a screw 113 which engages in theV recess 109. Theauxiliary piece has a notch orl cutaway portion 114 in its lower edgeproviding a rearwardly facing cam surface 115 and a forwardly facing'camsurface 116. On the inner side'of the left handv wall 28 of the receiverand atthe forward end thereof is a cam portion 117 adapted to extendinto the notch 114 of the auxiliary piece wheny the gun is closed. Thiscam porion 117 has cam surfaces 118 and 119 adapted to respectivelyengage the cam surfaces 115 and 116 on the auxiliary piece. It will beunderstood that, when the gun is opened or broken, the rear cam surface119 will engage the cam surface 116 on the auxiliary piece so as to movethe auxiliary pieceand the extractor vrearwardly and, during theope-rationof closing the gun,the cam` surface 118 will engage the camsurface 115 so that the auxiliary piece will be cammed forwardly to theposition shown in Fig. 1.

Provided on the barrel section, and, more especially, upon the take-downbracket 32, are actuators and 125, one for each extractor. Theseactuators are pivoted to the rearward endof the bracket 32 and straddlethe barrels, as illustrated in Fig. 3. lt will only be necessary todescribe the left hand actuator 125for, as stated, the ejectingmechanisms for the two barrels are similar. The actuator' 125 ispivoted, at its lower end, on a pin 126, the take-down lever beingnotched as at 127 so as to accommodate the actuator. Between theactuator 125 and a lug 128 on the bracket 32 is a plunger 129 and aspring 130 which normally tend to throw the actuator to the operatedposition shown in Figs. 2 and 5. The actuator is adapted to engage theforward end of the auxiliary piece. It hasV a shoulder 131 with which ascar 132 is adapted to cooperate to hold the actuatori in the operativeor cocked position shown inr Fig. 1. This scar is pivoted on a pin 133in a notch or slot -134 inthe bracket 32 and is normally urged intooperative position by a spring 135. The sear 132 has Va rearwardly anddownwardly projecting finger 136 which extends into a recess or groove137 in the curved face 31 on the rear end of the takedown bracket. Thebottom surface of this groove 137 constitutes' a cam.

The sear for the actuator 125 is controlled by the left hand hammer 71acting through a rod 140. This rod is made of spring material and isvlocated for sliding movement in an opening or bore 141`in the left handside wall 28 of the receiver. It, owing to its own flexibility,frictionally holds itself in any position of adjustment. The forward endof the rod is adapted to project beyond the 'curved face 24 at theforward lower corner of the receiver and into groove 137. The rear endof the rod has a head 142 provided with a slot 143 which receives theleft hand proj ecting end of the pintle 76 on which the hammers arepivoted. The slot 143 is of such length asv to properly limit the extentof movement ofthe rod. The rear end and upper edge of the head 142 has acam surface 144 with which a. pin or lug 145 extending laterally fromthe left hand hammer is adapted to engage so as to cam the rod forwardlyupon the cooking movement'of the hammer. The head of the rod, at itsrear end and at its lower edge, is bevelledY or inclined upwardly andinwardly as at 147, and the lug 145 has a bevelled face 148 which isadaptedto engage the bevelled face'147 of the rod when the'hammer isreleased tofire the gun.

The operation of the ejecting mechanism .for the over barrel Will now bedescribed, it

being understood that -the corresponding mechanism for the under barrelwill operate in a like manner. When the firearm is in the closedposition shown in Fig. 1, the. actuator 125 is held in cocked positionby the sear 132. The left hand hammer 71 is shown as having beenreleased to fire the shell. When so released, the cam surface 148 on thepro# jection 145 will cooperate with the upwardly and inwardly inclinedsurface 147 on the connecting rod 140 to flex the rear end of this rodlaterally and without moving the rod longitudinally. When the hammer isin the released position shown in Fig. 1, the projection 145is inoperative relation to the cam l' surface 144r on the head 142 of therod. Y When the gun is broken, the cooking lever will move the releasedhammer back tococked posi.-

ition, and when the hammer is so moved, the

projection 145 thereon, 'due to its engage` ment with the cam surface144, will move the rod 140 forwardly, thereby projecting the forward endof the rod into the groove 137 and into operative relation with the tailend 136 of the sear 132. Also during the operthis piece forwardlyindependently of the extractor and positively moving the actuator fromthe operated position shown inr Fig.

2 to the operative or cocked position shown in Fig. 1. Also, the camsurface at the bottom of the groove 137 in the rear face .of thetake-down lever will positively cam 'he connecting rod 140 rearwardlyfrom the position shown in Fig. 2 to that shown in Fig.

Y 1. Furthermore, upon closing movement of Cil w: liu

the gun, the surface 160 of the breech piece (and through which thefiring pins 161 extend) will engage the rear face of the plate 105 ofthe extractor and force the extractor to the forward position shown inFig. 1.

In. the event that one of the barrels has not been fired before thegunis broken, the ejecting mechanism associated with that barrel will notbe effected; that is to say, the actuator associated with thatbarrelwill be held in cocked position. For example, if th-etrigger-associated with the left hand hammer has not been pulled, andthe gun is broken, the proj ection11-5 on that hammer will remain belowthe head 1112 of the rod. Therefore upon breaking movementof the gun,the rod is not advanced to the position shown in Fig. Q, 'out on theother hand, will retain the retract-ed position shown in Fio. 1. Uponbreaking of the gun, the cam surface 119 will ngage'the cam surface l116and thereby nove the extractor to extract the shell withut 'liowevenejecting it. Upon closing movement of the gun, the auxiliary piece i lbe moved forward into operative relation to the cocked actuator by thecam surface 118, and the extractorl will be moved forward by itsengagement with the face 160 of the receiver. i

1t will he noted that the improved ejecting` mechanisms her-eindisclosed are characterized by their extreme simplicity in constructionand their cifcctivcness in operation. WJhon the gi i is taken down, thespace between the side walls 28 of the receiver is clear and tl ere areno projections extending from these side walls which are adapted to becaught and broken when handling or carrf-,Iing around the receiver intaken down con- Y dition. The actuators or ejectingl levers are carriedby the barrel section anc. particularly by the take-down lever. Accessmay be readily had to these levers. They are very compactly arranged onopposite sides of the barrel section, and the assembly and constructionare such that they do not require an increase in the width ofthe forearmin which they are housed when the gun is assembled. rlhe force requiredto move the connecting rod into Voperative position by the cookingmovement of the hammer or out of operative position upon closingmovement of "he gun is substantially negligible, a feature ofiniportance as it is. desirable to permit the gun to be closed andopened with little effort as possible. rllhe rod 140, when in operativei position, positively engages and releases the sea-i' 132 from theactuator. It will be ol served that the rod 1410 is moved positively inboth directions so that, in the event it should tend to stick, due todirt or corrosion, it will be caused to slide in the direction in whichit is urged.

Each actuator or ejecting lever is positively cockedupon closingmovement of the gun, and l such cocking movement is effected through theauxiliary piece. By the use of this separate a xiliary piece 111, theactuator may be given a relatively large movement without the use ofdistance inulti'piying` devices, and the cooking movement of theactuator is effected independently of, and without throwingany dutyonto, the extractor or shell when the same are cammed forwardly by theanvil face 160 upon closing movement of the gun. Upon initial closingmovement, the auxiliary piece and actuator are moved forwardly bythe camportion 117 with a relatively quick movement leaving the extractor 105behind, and upon further closing movement the anvil face 160 will engagethe head of the extractor (or the shell) camming the same forwardly, andduring` the entire closing movement of the gun there is always a spacebetween the extractor and the auxiliary piece. The auxiliary pieceengages the actuator adjacent the free end of the latter, and theinterengaging` cam surfaces 115 and 118 Vare spaced a considerabledistance from the pivot pin 29 which means that relatively largeleverages are employed in cooking the lever so that the gun may be moreeasily closed. The actuator has a swinging movement through a relativelylarge arc, thus permitting the spring 180, when the actuator is cocked,to be .properlycompressed, and insuring that the actuator, whenreleased, will impart a. movement tothe extractor which Vwill surely andcompletely eject a fired shell.
